its more likey the front concrete weight at the front, depending on the damage done, you may be able to retighten the bolts holding it, other wise you will have to take the complete tub assy out, to change the front plate, normally you have to change the complete tank assy, which needs a mode kit, if the machine is under 5 years old - try getting hvr out ( cost about £110 ) labour cost - but parts are free
Hope this helps
